Abstract (en)
[origin: US2019257251A1] The invention relates to a combustion chamber for a turbomachine. The combustion chamber comprises at least one spark plug, at least one fuel injector of a first type of injector that is located facing the spark plug, and at least one fuel injector of a second type. Each fuel injector comprises a mobile sealing member that is configured to open when the fuel pressure exceeds an opening threshold. The opening threshold of the mobile sealing member of the injector of the first type is strictly less than the opening threshold of the mobile sealing member of the injector of the second type.
